Several ancient Sanskrit documents credit sages Agastya and Bharadwaja with establishing the principles for aircraft construction. In fact, there are references to ancient ‘flying machines’ that are very similar to modern day hot air balloons (called a “Chchatra”) and parachutes (called a “Vimandvigunam”).
The Vaimanika Shastra further reveals that the aeroplanes took off vertically, indicating that some form of anti-gravity technology was utilized in their construction. There is also reference to a liquid propulsion agent, most likely gasoline that propelled the aeroplane through air.
In this manner, as we research ancient texts, there are several authentic mentions and clear proof of existence of airplane (aeroplane) and aviation technology during the Vedic times.
